ISOW7821FDWER

The ISOW7821FDWER is a high-performance, reinforced digital isolator with an integrated DC-DC power converter, manufactured by Texas Instruments. It provides galvanic isolation of up to 5000 VRMS between two sides of a circuit, ensuring safety and noise immunity in industrial and medical applications. It supports high-speed data communication up to 100 Mbps, making it ideal for isolating digital signals in noisy environments. The built-in transformer-based power converter supplies a regulated output voltage (3.3 V or 5 V), allowing isolated power delivery alongside data isolation, reducing external component count and board space.

This device is widely used in industrial controls, motor drives, medical equipment, and test instrumentation where safety and signal integrity are critical.
